现在，我想做的是，如果用户在textboxahsan中输入了一些内容，然后添加按钮启用，如果TextBoxOnBlur中没有任何内容，则添加按钮将自动禁用

    function checkdata() {
var ok = true;
        $("#TextBoxesGroup :input").each(function () {

            if (!$(this).val()) {             
               ok = false;
               return;
            }

        });
if (ok) $("#addButton").removeAttr("disabled");
else   $("#addButton").attr("disabled", "disabled");

    }

    $(document).ready(function () {
        $("#addButton").attr("disabled", "disabled");

            $("#TextBoxesGroup :input").blur(function () {
                checkdata();
            });

    });
</script>
</head>
<body>
<div id='TextBoxesGroup'>
    <div style="float: left; width: 625px;">
        <div>

<div>
    <input type="button" value="Add New Row" class="qa-adbtn" id='addButton' />
</div>

</html>

    function checkdata() {
var ok = true;
        $("#TextBoxesGroup :input").each(function () {

            if (!$(this).val()) {             
               ok = false;
               return;
            }

        });
if (ok) $("#addButton").removeAttr("disabled");
else   $("#addButton").attr("disabled", "disabled");

    }

    $(document).ready(function () {
        $("#addButton").attr("disabled", "disabled");

            $("#TextBoxesGroup :input").blur(function () {
                checkdata();

这很有效

    function checkdata() {
var ok = true;
        $("#TextBoxesGroup :input").each(function () {

            if (!$(this).val()) {             
               ok = false;
               return;
            }

        });
if (ok) $("#addButton").removeAttr("disabled");
else   $("#addButton").attr("disabled", "disabled");

    }

    $(document).ready(function () {
        $("#addButton").attr("disabled", "disabled");

            $("#TextBoxesGroup :input").blur(function () {
                checkdata();
            });

    });

    function checkdata() {

检查以下小提琴：

使用按键事件，如果txtbox的长度更大，则启用按钮

在Fiddle中，默认情况下，我将按钮保持为禁用状态。您可以根据需要进行适当的更改。

检查以下Fiddle：

    function checkdata() {
var ok = true;
        $("#TextBoxesGroup :input").each(function () {

            if (!$(this).val()) {             
               ok = false;
               return;
            }

        });
if (ok) $("#addButton").removeAttr("disabled");
else   $("#addButton").attr("disabled", "disabled");

    }

    $(document).ready(function () {
        $("#addButton").attr("disabled", "disabled");

            $("#TextBoxesGroup :input").blur(function () {
                checkdata();
            });

    });
